iphone - touchesMoved工作速度不够快

我希望当用户从左向右滑动时，标签计数器从1更新为5。如果我缓慢滑动，则它会非常缓慢地工作，然后会更快地工作，那是行不通的吗？还有另一种方法可以实现吗？

我有这个代码：

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    gestureStartPoint = [touch locationInView:self.view];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [touches anyObject];
    CGPoint currentPosition = [touch locationInView:self.view];

    if ((int)(currentPosition.x)%40 == 0 && counter < 5) {
        counter++;
    }

    [label setText:[NSString stringWithFormat:@"%d", counter]];

}

最佳答案

您可以使用UIPanGestureRecognizer ...它具有开始状态，更改状态和结束状态，例如touchEvents...。

- (void)onDraggingLetter:(UIPanGestureRecognizer *)panGR {

    if (panGR.state == UIGestureRecognizerStateBegan) {

    } else if (panGR.state == UIGestureRecognizerStateChanged) {

    } else if (panGR.state == UIGestureRecognizerStateEnded) {

    }
}
